Teams handling regulated data who need proof that sensitive emails were opened, not just sent, should consider Beyond Encryption Mailock® Secure Email; message tracking and revocation give you the audit trail that generic TLS encryption cannot. AES-256 encryption with multi-factor recipient verification covers the NIST PR.DS and PR.AA controls auditors actually ask for. Skip this if your priority is preventing internal data exfiltration rather than securing external communication; Mailock assumes the recipient's inbox is the trust boundary, not an extension of your network.

ShareFile Email & File Encryption

SSAE 16 Type II certification and 256-bit encryption covering data in transit and at rest address the PR.DS requirement, while its 100 GB secure sharing ceiling handles most compliance workflows without friction. Skip this if you need granular audit trails and revocation controls; ShareFile encrypts well but treats governance as secondary to ease of use.
